How do you structure your quotes?

Aaron · 12-30-2007, 08:51 PM

I like to make all strings with double quotes, and use single quotes for HTML tags. Quotation marks in strings are done with "

So, I structure my echo statements like so:

PHP Code:


			
echo "<p span='font-size=3em;'>Two is the number two.  You want to say too as in &quot me too &quot</p>";

For me personally, if it has a PHP variable in it, I'll use double-quotes, if not, single quotes. All SQL statements use double quotes.

eg:

PHP Code:


			
echo 'Hello World';



echo "Hello $firstname";



$sql = "SELECT something FROM somewhere";

Edit: I also have a habbit of breaking out of strings for variables - eg:

PHP Code:


			
echo 'Hello ' . $firstname . ' Welcome to my site!';

So I generally only use double quotes for SQL statements

I use single quote for everything I do in PHP and double quotes for my HTML attributes.

I use:

PHP Code:


			
echo('Hello my name is<strong>' .$name. '</strong>');

Is that just a particular quirk, or does it seem more neat to you?

CMellor · 12-31-2007, 03:11 AM

Me personally, it's about neatness. I'm a neat freak, even with my code. Having my variables outside of quotes, it colour codes it, meaning it's easier to spot.

Also, with single quotes, the variables will be treated literally, so:

PHP Code:


			
$var = 'hi';
echo '$var'; // prints $var
echo "$var"; // prints hi
echo 'hi'.$var.'hi'; // prints hihihi

Aaron · 12-31-2007, 06:19 AM

Yes, but the same goes for

PHP Code:


			
echo "\$var";

I agree with Chris on this - breaking out of strings for variables does look a lot neater to me (and my IDE's colour syntaxing) than having them inline.

I'm very anal about laying out of code. Pretty much all strings are wrapped in single quotes; concatenating strings and variables with single spaces between the string and variable, and variable and string (or two variables, or whatever). Basically:

PHP Code:

// Me likey
$string = 'This string is ' . $colour;

// Me no likey
$string = 'This string is '.$colour;
$string = 'This string is '. $colour;
$string = 'This string is ' .$colour;
$string = "This string is $colour";

// Evil!
$var = 'colour';
$string = "This string is ${$var}";

// Super Evil! Even worse than the above!!
$string = "This string is " . $colour;

Also, since there has been a fair amount of echoing concatenated strings in this topic: remember that you can separate expressions with a comma when using echo!

PHP Code:

echo 'This string is' . $colour;
echo 'This string is', $colour;

The latter (with commas) forgoes the overhead of first concatenating the elements together into one long (in relative terms) string then echoing it, in favour of outputting a series of smaller strings: the upshot being that it is marginally faster to process.

Cool, I never knew that
